Moss with sporophyte
WebAfter elongation of the moss sporophyte has ceased, the distal portion (farthest away) enlarges to form the capsule (sporangium), or spore-bearing region. The spores (meiospores), which arise by meiosis, are shed from the capsule gradually through a variety of mechanisms.After the operculum (cover) of the capsule has been shed, its mouth is … WebIn moss gametophyte is the more prominent generation represented by the plant itself and the protonema; and sporophyte represented by sporogonium is partially dependent or semi-parasitic on the gametophyte. Calyptra, the temporary hood on the capsule, the most important part of sporophyte, really belongs to gametophyte.

WebNov 3, 2024 · Jutting out of moss leaves, these stalks are known as sporophytes; each sporophyte contains a capsule of spores at its outermost end. As wind and water carry these spores away from their source ... WebMosses are bryophytes and have no proper stem or roots. It has two parts sporophyte and gametophyte. The sporophyte stalk, called the seta, bears the spore capsule on its tip. The capsule top ruptures and falls off to discharge mature spores for producing new plants. Gametophyte contains balls of unspecialized cells called gammae.

WebPolytrichium: hairy cap moss. Gametophyte plants (green), a few with sporophytes emerging from the top of female plants. Polytrichium is a common moss that occurs across all of North America. It is large for a moss and regularly exhibits both the haploid and the diploid phases of its life cycle. Thus it is a useful example of what mosses are about. WebApr 7, 2024 · The life cycle of mosses shows alternation of generation. They consist of only a single set of haploid chromosomes. The period when the moss plant has two paired chromosomes is known as the sporophyte stage. The life cycle starts with the sore, which is haploid and resulting in the production of protonema. Protonema is the thallus-like, flat ...
WebIn mosses, the male gamete (sperm released from antheridia) fuses with the female gamete ( egg cells within the archegonium) to result in the immature sporophytes. The sporophyte matures and releases the spores. These spores germinate to form the protonema (an immature transitory stage), that matures into the gametophore (gamete bearing structure).
WebApr 15, 2024 · In moss sporophyte plant, spores are produced in a capsular structure known as sporangium. The sporangium is attached to the gametophyte and obtains its nutrition with the help of a small stalk known as seta (Figure 2).
